Patented July 1, 194-1 SPINNING AND TWISTER RING George Goodchild, Saco, Maine, assignor to Saco- Lowell Shops, Boston, Mass., a corporation of Maine Application October 31, 1939, Serial No. 302,102

Claims.

This invention relates to rings of the type used in spinning and twister frames for the purpose of supporting and guiding and revolving travellers employed in performing the spinning and twisting operations. For convenience both types of machines and the rings used in them will be hereinafter included in such terms as "spinning frames, spinning rings, and the like.

In connection with the spinning operations, and particularly in the production of fine yarns, it is important to have each ring and the spindie with which it cooperates, supported in an accurate vertical relationship to each other so that the turns or convolutions of yarn Wound on the spool or other yarn supporting body mounted on the spindle will be placed accurately with reference to both the upper and lower shoulders of the spool. This result can be accomplished at one end of the traverse of the ring rail by the mechanism which supports and operates it, but it must be accomplished at the opposite end of the traverse by the vertical adjustment of the ring or spindle. The usual method of producing such adjustment is to place shims of suitable thickness between the spindle base and the spindle rail.

It is the chief object of the present invention to devise a more satisfactory means for accomplishing this result.

The nature of the invention will be readily understood from the following description when read in connection with the accompanying drawing, and the novel features will be particularly pointed out in the appended claims.

In the drawing,

Figure 1 is a plan view of a spinning ring and a holder therefor constructed in accordance with this invention; and

Fig. 2 is a transverse, vertical, sectional view through one side of the ring and its holder, showing these parts on a larger scale.

The construction shown in the drawing comprises a ring holder 2 adapted to be secured to the upper surface of a ring rail 3 in any convenient manner as, for example, by screws extending through the holes in the lugs or ears 4-4. Mounted in this holder is a ring 5 which may be of any suitable form, that shown being of the general type illustrated in my Patent No. 2,145,478. That is, it includes an oil groove 6 extending entirely around the main body of the ring and normally closed by an annular cover 1 of translucent or transparent material.

According to the present invention the outer edge of the ring 5 is screw-threaded, as clearly shown in Fig. 2, while the ring holder 2 is provided with an inwardly projecting flange portion 8, the inner edge surface of which also is screwthreaded to take the threads of the ring. Consequently, the ring can be readily mounted in the holder merely by threading it into the latter, and it can be adjusted vertically through a very substantial distance, and with a high degree of accuracy, to exactly the position required to cooperate in the desired manner with the spool or other thread supporting body mounted on the spindle which cooperates with the ring.

In order to clamp the ring in any adjusted position, the holder preferably is made in the form of a split ring; that is, it is cut at one side, as shown at 9, Fig. 1, and a screw It is passed i'reely through one of two outwardly projecting ears at opposite sides of the cut and is threaded into the other ear where it is operable to contract the holder and thus to clamp it on the ring.

With such an arrangement, therefore, the labor involved in adjusting the relative heights of the rings and spindles of a spinning frame is greatly reduced, and the making of such adjustments accurately is facilitated. At the same time the expense of manufacture of the ring and its holder are kept within entirely practical limits.

Having thus described my invention, what I desire to claim as new is:

1. A spinning ring structure comprising a ring holder adapted to be secured to a ring rail and a ring mounted in said holder, the outer peripheral edge of said ring being screw-threaded the holder having a, cooperating screw-threaded portion to receive the threaded edge of said ring, said holder being split transversely, and means cooperating with the split section of said holder to contract it upon said ring and thereby to secure the ring in its various positions of adjustment.

2. In a spinning frame, the combination with a ring rail, a spinning ring, a ring holder, and means for securing said ring holder on said rail, said holder having screw-threaded engagement with said ring supporting the latter for vertical adjustment relatively to said rail.

3. In a spinning frame, the combination with a ring rail, a spinning ring, a ring holder, means for securing said holder on said rail, said holder and said ring having cooperating parts supporting said ring for rotary adjustment around its own axis into different vertical positions relatively to the rail.

4. In a. spinning frame, the combination with holder being of annular form, and having an internally threaded approximately vertical inner surface, and a spinning ring having an externally screw-threaded surface cooperating with said 5 screw-threaded portion of said holder to support said ring in said holder for vertical adjustment relatively thereto.
